I previously used a 500mm FL Equinox 80 fitted with the Lakeside focuser. I was able to use the V-Curve set-up and Local-Field focusing successfully.
I have now switched to an Esprit 120 with 840mm focal length using the same Lakeside focuser, and am having trouble with autofocus.
The focuser runs smoothly under manual control with no sign of slipping or sticking. I have calibrated the Lakeside focuser for the new telescope and put the limits into the Robofire tab in Voyager.
However, I can’t get the V-Curve First Light Wizard to work. It does one side of the V-Curve and then stops. Without a calibrated V-Curve I can only use LocalField mode in manual, but that does not work either. I can focus pretty well by moving the focuser manually under Voyager, and the scope holds that focus across the sky and over time. No sign of slipping. I can also move away from the focus and come back to the same point with the same HFD. So the focuser seems to be working OK, it is just the autofocus that is the problem.
I am far enough North that we only get nautical dark at this time of year. I read somewhere that robofire needs clear dark skies for calibration. Could that be my problem, and does it mean that I will have to wait until late summer when we get astronomical dark back?
The Robofire Configuration settings for V-Curve are these (in case I have made an incorrect setting somewhere:
